can the upbox or raise match the print quality of zortrax?
Back on topic :-)
They can, but it depends...
Nightshift mentioned the Raise would need tweaking, I do not agree if it is about what I print.
There are many mods published already and they all might show enhancements but I did not go into any right now since I did not need it.
Good thing is you can mod and this is supported with much information from the manufacturer, an unthinkable way to go here.
I would tell that the out of box experience of the M200 is better for folks that did not have much printing experience before or do not want to dig too deep into 3DP settings.
Knowing this, one should still be aware that this 'ecosystem' is also the limit and you have a hard time if you want to go beyond that.
At the opposite with the Raise, just the sky is your limit. Up! has loosen some restrictions (opened the software), but I did not use the recent hardware and software.
If it is about the M300 I would bet that not only the print volume will increase but also the problems you have with such large prints and Z-Materials.
Not talking about Z-ABS because it looks like it will not be officially supported (what stops you from printing it anyway?), but except Z-HIPS I think all other materials will show much tendency to warp on a 30cm flat object.
The M300 will be uncovered on it's top, you may have seen prints fail on your M200 that do not use more than half of the bed's area.
Imaging such a print on an M300 with Z-Material (see picture). The raft is 280x165mm, printed PLA.
BTW. none of them causes radioactivity or thermo nuclear explosions (good thing to know).
